| | + | The Bible provides a clear link between the adherence of a family or a nation to the laws of God and the moral choices of offspring. (Prov. 22:6) The Bible also positively examples close father-son and familial relationships, and may be seen to partially implicate detachment with rebellion. (Gn. 37-50; 2 Sam. 13-18) Studies today have shown that [[Religious Upbringing and Culture Affects Rates of Homosexuality|religious upbringing and culture can strongly affect rates of homosexuality]]. |

| − | Chromosome linkage studies of sexual orientation have indicated the presence of multiple contributing genetic factors throughout the genome. In 1993, Dean Hamer and colleagues published findings from a linkage analysis of a sample of 76 gay brothers and their families. Hamer et al. found that the gay men had more gay male uncles and cousins on the maternal side of the family than on the paternal side. Gay brothers who showed this maternal pedigree were then tested for X chromosome linkage, using twenty-two markers on the X chromosome to test for similar alleles. In another finding, thirty-three of the forty sibling pairs tested were found to have similar alleles in the distal region of Xq28, which was significantly higher than the expected rates of 50% for fraternal brothers. This was popularly dubbed as the 'gay gene' in the media, causing significant controversy. Sanders et al. in 1998 reported on their similar study, in which they found that 13% of uncles of gay brothers on the maternal side were homosexual, compared to 6% on the paternal side.

| | + | The belief that homosexuality has a biological cause can be traced back to the preliminary findings of neuroscientist Dr. Simon LeVay. In 1991 LeVay's studied the brains of 41 cadavers which included 19 homosexual males, and claimed that "a tiny area believed to control sexual activity [the hypothalamus] was less than half the size in the gay men than in the heterosexuals."<ref>Charlene Crabb, ''Are Some Men Born to Be Homosexual?'', U. S. News & World Report, 9 September 1991, p. 58</ref><ref>S. LeVay, "A Difference in Hypothalamic Structure Between heterosexual and Homosexual Men," Science 253 (1991), pp. 1034-37</ref> This study was immediately seized upon by many as proof that homosexuality was biologically determined. |
| | + | |
| | + | However, further scrutiny showed this hasty conclusion as lacking in warrant. |
| | + | |
| | + | *1. The range of sizes of the hypothalamic region varied and was inconsistent. The region at subject was the same size in a few homosexual men as that of the heterosexuals, while in a few other heterosexuals this region was a small as that of a homosexual. |
| | + | *2. The fact that all 19 of the homosexual men had died of [[AIDS]] could easily have accounted for or contributed to the differences. |
| | + | *3. It has not been determined if the smaller hypothalamuses were the cause rather than the effect of homosexual activity. "Researchers have found that when people who become blind begin to learn Braille, the area of the brain controlling the reading finger actual grows larger."<ref>Reported in D. Gelman "Born or Bred?" Newsweek, 24 February 1992, pp. 46-53</ref><ref>http://www.leaderu.com/orgs/probe/docs/homotheo.html</ref> |
| | + | *4. Levay's study was based study was based upon a supposed sexual functional correlation between the SDN-POA brain center in male rats and a brain center called INAH3 in humans, but which assumption was shown to be false.<ref>http://www.biblebelievers.com/Cameron4.html</ref> |
| | + | *5. The sexual history of the "heterosexual" men was not known, and Levay's samples included 16 brains from men whose sexual orientation was unknown.<ref>[http://www.equip.org/PDF/DH055-1.pdf Joseph P. Gudel, ''HOMOSEXUALITY: Fact and Fiction'']</ref> |
| | + | *6. And as William Byne noted, LeVay’s work "has not been replicated, and human neuroanatomical studies of this kind have a very poor track record for reproducibility. Indeed, procedures similar to those LeVay used to identify nuclei have previously led researchers astray".<ref>Byne, William (1994), “The Biological Evidence Challenged,” Scientific American, May, 1994, 270: p. 53</ref>. |
| | + | *7. The conclusions were that which were sought by the researcher. Dr. LeVay, a homosexual himself, confessed that his study was not entirely a dispassionate scientific endeavor,<ref>Simon LeVay on The Phil Donahue Show, ''Genetically Gay: Born Gay or Become Gay?'', January 3, 1992</ref> He also later stated, "I did not prove that homosexuality is genetic, or find a genetic cause for being gay."<ref>Byrd, A. Dean, Shirley E. Cox, and Jeffrey W. Robinson (2001), ''Homosexuality: The Innate-Immutability Argument Finds No Basis in Science'', The Salt Lake Tribune</ref><ref>http://www.sltrib.com/2001/may/05272001/commenta/100523.htm</ref> |

| | + | Two prominent geneticists, Paul Billings and Jonathan Beckwith, commenting on the quality of the LeVay research, stated that LeVay, "could not really be certain about his subject's sexual preferences, since they were dead", and that his "research design and subject sample did not allow others to determine whether it was sexual behavior, drug use, or disease history that was correlated with the observed differences among the subjects' brains." And in addition, it was very likely that LeVay's method of defining homosexuality would "create inaccurate or inconsistent study groups." <ref>P. Billings and J. Beckwith, "Born Gay?" Technology Review, July 1993, p. 60,61</ref> |

| | + | Another study, published in ''Proceedings of the National Academy of Science of the United States of America'', examined the ''anterior commissure'' (a structure that divides the left and right halves of the brain) of male heterosexuals and homosexual men, most of whom died of AIDS. The study shows that the anterior commissure was larger in women and in 27 of the 30 homosexual men than in heterosexual men.<ref>L. Allen, et al., ''Sexual Orientation and the Size of the Anterior Commissure in the Human Brain,'' Proceedings of the National Academy of Science of the United States of America 89, no. 15 (1992), pp. 7199-7202</ref>. |
| | + | |
| | + | Here again, how AIDS might have factored in this difference is an issue, and the findings of this study were overall in contradiction to another study published in 1988, which found, in part, that the anterior commissure was larger in men than in women.<ref>S.

| − | A recent study suggests linkage between a mother's genetic make-up and homosexuality of her sons. Women have two X chromosomes, one of which is "switched off". The inactivation of the X chromosome occurs randomly throughout the embryo, resulting in cells that are mosaic with respect to which chromosome is active. In some cases though, it appears that this switching off can occur in a non-random fashion. Bocklandt et al. (2006) reported that, in mothers of homosexual men, the number of women with extreme skewing of X chromosome inactivation is significantly higher than in mothers without gay sons. Thirteen percent of mothers with one gay son, and 23% of mothers with two gay sons showed extreme skewing, compared to 4% percent of mothers without gay sons.
